The compilers errors I was getting the past few days was for using the NODRAW texture to "paint" the back of my world brushes. While having the "portal2" keyword enabled.

Basically, when you have the "portal2" keyword and then you type "nodraw" in the filter, you get a NODRAW-like texture... which is actually called "tools/toolsnodraw_glass_footsteps" which is a translucent material, therefore not valid as a world seal for BSP.

Really...
If anyone has gone through the same **** as me I hope this post will be useful.

That explains the problems in my old map I was making, then I stopped because of this problem. :smith:

What kind of prop do I need to make something to make it able to be picked up, or at least fall when its dropped? I'm trying to get the potato trophy to fall from a door, and prop_physics doesn't like me

Trigger_catapult just isn't working for me at all.
Are you using v5 of the fgd?

No,I am using v4,but I just copied that faith plate from coop map,no more editing,just putted it in place.http://www.mediafire.com/?wnr1j36x6ijdl55
here is my map,where it works.
There is some "????" flag in catapult,because Valve have real Portal 2 fgd,so they have all flags.
So its different if you create it in Alien swarm,or copy it from Valve map.

My only problem is. I can't figure out how to "put" a portal - able surface on a existing wall instead of creating a plate in front of it, so you can create portals on one area while the other part is nonPortal. Or could I just simply remove a PART of the Wall?
